Question about Toshiba 57H82 57" Rear Projection Television

1 Answer

Picture too dark

We recently had our TV serviced and they replaced the 3 color chips. Now our picture is far too dark. We can barely see faces in night time scenes. The repairman said it was the quality of the shows; however, the same shows and movies look great on our less expensive, non-HD TVs. We have tried all of the adjustments an nothing helps. Please advise.

There are only 2 chips for colour convergence in this unit. there is also a screen control on each tube but most of all there is a bleeder assy. that can control the brightness.

Hey everyone. I have a Hitachi Rear projection Tv 53udx10b. I just replaced the convergence chips and cleaned all 3 CRT tubes. The picture definitely looks clearer now but the white tint has a slight...


You can try adjusting the color output. There are two ways to do this:
1) In the service menu (I don't know the codes or parameters...) I will not cover this for lack of info.

2) Via the focus block (Very touchy and difficult to get the mix right again if you get too far off)

If you take off the front cover there should be a access panel. Behind that, there should be a small square black box with 6 screws on it. This is the focus block. (At least this is where most of them are located)

It sounds more like you may need more red in the mix or just less blue and green. There is a screw for each color. Do not mess with the focus screws, just the ones labeled 'SCREEN.'

Barely turn the red up.
Use an insulated screwdriver and DO NOT TOUCH the focus block and ESPECIALLY NOT the back of it.
Very HIGH VOLTAGE. I found that out the hard way.

Do not turn andy of these up too high or damage may occur and the TV may detect a short and shut off.

I have found that if the three colors are adjusted in a dark room to where the 3 color spots (R/G/B) are just barely visible on the screen at equal levels, there is a pretty good color balance.

I hope this helps! Just be careful.

Fuzzy picture and dark picture and color seperation when hot.


The colors seperating is a convergence problem, as far as being dim this may be related but the TV likely needs service adjustments.

convergence output IC problem. convergence board would have to be removed - remove and replace 2 STK IC's and check the surrounding resistors. Shops usually $200-$400 Be sure to vote/rate me if this helped Thanks!

The dark color of my tv was change unspected the dark color now are blue, violet,and other exept black, the dark scense can't see. please help me.


I believe you either have a bad LCD Controller Board or a bad Main Board. The only way to know is to replace one. If it doesn't fix it , replace the other. Or replace both and it should be fixed.
I hope this helps,

Dark colors Picture going out


It is hooked up to Direct TV. When I change the channel on the TV to another input it looks fine but without a picture. as you do not see tint in another channel means your color section is ok it is due to video or luminance section.
